Comparison of Standard Versus Low Dose Advagraf® With or Without Angiotensin-converting Enzyme Inhibitor (ACEi)/Angiotensin Receptor Blocker (ARB) on Histology and Function of Renal Allografts

Phase 3
Completed
Conditions
Kidney Transplantation
Interventions
Registration Number
NCT00933231
Lead Sponsor
Astellas Pharma Inc
Brief Summary

This is a multicentre study examining the use of Advagraf-minimization strategy and/or the use of an inhibitor of the renin-angiotensin system in reducing chronic rejection in renal allografts.

Detailed Description

The study will consist of the following 4 treatment groups.:

1. Standard dose Advagraf with angiotensin-converting enzyme inhibitor (ACEi)/angiotensin receptor blocker (ARB) antihypertensive therapy

2. Standard dose Advagraf without ACEi/ARB antihypertensive therapy

3. Low dose Advagraf with ACEi/ARB antihypertensive therapy

4. Low dose Advagraf without ACEi/ARB antihypertensive therapy

Inclusion Criteria
  • Subject is the recipient of a first or second deceased or living donor renal transplant (one kidney only)
  • Subject must have at least one HLA-mismatch with the donor. HLA identical donor-recipient pairs are not eligible
  • Subject understands either English or French
  • If female and of child-bearing potential, subject has a negative pregnancy test and utilizes adequate contraceptive methods
Exclusion Criteria
  • Presence of donor specific antibody
  • Subject who is currently participating in a study with investigational drug, or who has received investigational drug within three months prior to randomization. Observational studies are acceptable
  • Subject who has lost a previous graft for immunological reasons less than one year from transplant
  • Subject is pregnant or breastfeeding
  • Subject receives a kidney lacking pre-implantation biopsy
  • Subject has significant disease (e.g. malignancy or uncontrolled infection) or disability (e.g. cognitive defect) which prevents understanding of, or adherence to the protocol
  • Subject who in the opinion of the Investigator, require ACEi/ARB therapy post-transplant for any indication
  • Subject who requires induction with Thymoglobulin, Campath, antithymocyte globulin (ATG), antilymphocyte globulin (ALG) or any biological induction agent other than basiliximab. Unplanned post-transplant use of these prohibited drugs for clinical indications post-transplant is allowed
  • Subject has plans to become pregnant within 2 years post-transplant
  • Subject who has a positive T-cell or B-cell crossmatch. Subjects with a weakly positive B-cell cross-match that tests negative following DTT reduction are acceptable
  • Subject who has a requirement for maintenance immunosuppressant therapy with the exception of low dose steroid or mycophenolate mofetil (MMF). A subject who is on low dose tacrolimus maintenance therapy will be eligible provided the tacrolimus is withheld at least 1 week prior to transplant
